Hello,
I have ThinkPad T480s and after latest kernel upgrades on Rawhide I
see something like:
```
exit_boot() failed!
efi_main() failed!
```
Right after grub and then system reboots.
I found on the internet that passing `efi=no_disable_early_pci_dma`
could help and it actually did!
Anybody else saw this issue? Any ideas if this could be worked around
in Fedora kernel?

What's the kernel NVR?
CONFIG_EFI_DISABLE_PCI_DMA has been disabled since its arrival so this
is pretty odd.

Hi Igor,
I did not read Fedora list often, just catch this now. Maybe you have
noticed the fix then just ignore my reply.

This has been fixed by below upstream commit:
105cb9544b16 efi/x86: Move efi stub globals from .bss to .data
But during the discussion about the fix, people pointed out grub in
distribution should fix potential other bugs although the kernel commit above
fixed the current issue:
